Rep. Tulsi Gabbard, one of the Democrats seeking the party’s nomination for president in 2020, sued Google on Thursday for suspending her advertising account, NBC News reported.

The lawsuit adds to a chorus of bipartisan complaints against Google and other tech companies over the power they’ve accumulated as censors and gatekeepers in areas such as politics, advertising and free speech.

Lawyers for Gabbard, D-Hawaii, filed the suit in federal district court in Los Angeles.

According to the suit, Google suspended Gabbard’s advertising account without warning June 28, hours after the end of a Democratic presidential primary debate in which she participated. She alleges that Google gave conflicting and false reasons for the suspension before reinstating the account hours later.
